LAMP-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 481,268, dated August23, 1892.

Application filed November 2, 1891. Serial No. 410,681. (No model.)

To all whom it may concern.-

Be it known that I, JOHN B. PRICE, of lVollaston, in the county ofNorfolk and State of Massachusetts, have invented certain new and usefulImprovements in Lamp-Extinguishers and I do hereby declare the followingto be a full, clear, and exact description of the invention,such as willenable others skilled in the art to which it appcrtains to make and usethe same.

My invention relates to an improvement in lamps, and more particularlyto means for causing the light to be automatically extinguished in casethe lamp is jarred or overturned, the object of the invention being toproduce simple and efficient devices for the accomplishment of thepurpose above stated, which devices shall be comparatively cheap tomanufacture, easy to assemble, and which shall be effective in theperformance of all their functions.

lVith this object in View the invention consists in certain novelfeatures of construction and combinations and arrangements of parts, ashereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical sectional view ofthe body of alamp having my improvements applied thereto. Fig. 2 is asection on the line w 00 of Fig. 1. Figs. 3, 4, 5, 6, and 7 are detailviews. Fig. 8 is a view of a modification.

A represents the body of a lamp adapted for the reception of oil, suchas kerosene, said body A being provided at its upper end with aninternally-screw-threaded neck a for the reception of thesimilarly-threaded shank of a lamp-burner B, which latter is providedwith a wick-tube b and wick raising and lowering device 0. Adapted toloosely embrace the upper end of the wick-tube, so as to have a verticalmovement thereon, is a short tube (:1, having laterally-projecting arms01, from the outer ends of which arms (2 depend and, passing through theburner B, terminate just above the top of the lamp-body, said tube d andarms d and d constituting an extinguisher which when moved above the topof the wick by the means hereinafter described will extinguish the lightinstantly. Located within the lamp-body at diametrically-opposite sidesthereof are two tubes 6 e, at the lower ends of to make contact with thedepending arms d of the extinguisher, and thus raise said extinguisherto extinguish the light on the wick. The chamber or receptacle 0 issupported by means of the upwardly projecting annular flange v1 of acasing D, which flange i is provided with an L-shaped slot j for thereception of a pin or projection j on the interior of the body, wherebythe receptacle or chamber C will be properly supported and the casing Dretained in proper position.

7 Located in the lower end of the body A of the lamp is a bracket E,comprising arms 1 1, 2, and 3. The upturned ends of the arms 1 l areprovided with sockets for the reception of the lower ends of the rods g.The arm 2 extends upwardly through a perforation in the lower end of thereceptacle or chamber 0, and the arm 3 projects downwardly through thecasing D at the bottom of the lamp, its end being adapted to enter asocket-piece 4. A spiral spring 5 encircles the arm or rod 3 and tendsto normally force said arm and the bracket of which it is a memberupwardly. The bracket E is maintained normally at the lower extremity'ofits movement by means of a weight or ball F, located in the conicalchamber or receptacle G, and said chamber or receptacle being of aconical form the ball or weight F will rest upon the upper end of theously explained. By providing the ring 7?. the raising of theextinguisher is rendered certain,whereas if small plates were providedto engage said extinguisher they might not always be in line with thearms (1 of the extinguisher, as the lamp-burner might not always bescrewed on to the full extent.

The object of making the ends of the wires 1 l of bracket E with socketsto receive the ends of the rods gis that it facilitates manufacture andallows the lamp to be taken apart for exhibition or cleaning. Byunelasping the lower casing D the spiral spring may be removed, thebracket E can be separated from the rods g, and when that is done theballsupporting receptacle 0 can be removed. By removing the lamp-burnerB the ring it can be removed.' As shown in Figs. 6 and 7, theextinguisher may be made in one piece and bent as shown in said figures.

Instead of locating the spiral spring in the casing D, said casing maybe dispensed with, as shown in Fig. 8, and two spiral springs 5 locatedon the rods g, one end of said springs bearing against the ring h andthe other ends of said springs bearing on lugs 7, connected to said rodsand encircling the body of the lamp. Other lugs 9 will in this case beprovided near the lower end of the lamp-body and provided with loops,through which the rods g pass. In this construction both rods g may bemade of a single piece of wire.

It will be seen that when the lamp is placed upright the ball or weightF will roll to the center of the receptacle 0 and depress the bracket E,and thus release the extinguisher and permit it to drop, so as to exposethe wick. Should the extinguisher fail to drop byits own gravity, it maybe readily forced down by hand.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination, with a lamp, of an ex tinguisher adapted to embracethe wick-tube, rods extending parallel with the body of the lamp andadapted to engage the extinguisher, a bracket connected with said rods,a spring adapted to normally force said bracket and rods upwardly, and aweight adapted to automatically maintain said rods normally out ofcontact with the extinguisher against the tension of said spring andautomatically release said bracket and rods when the lamp is jarred oroverturned and cause the extinguisher to be elevated to extinguish thelight, substantially as set forth.

2. The combination, with a wick-tube, an extinguisher embracing thistube, and devices projecting outwardly from this extinguisher, of a ringsurrounding a portion of the burner and adapted to move up and drawthereon and located in position to strike these projecting devices whenit moves out of its normal position and means for locking the ring, saidmeans being located and arranged to automatically unlock the ring whenthe lamp is suddenly jarred or tilted out of its perpendicular position,substantially as set forth.

3. The combination, with a lamp and an extinguisher adapted to embracethe wick-tube, of rods adapted to run parallel with the lampbody andengage said extinguisher, a receptacle having a conical bottom locatednear the lower end of the body of the lamp and adapted to produce thebottom of the oil-receptacle, a spherical weight within said receptacle,a bracket connected with said rods and having an arm adapted to projectthrough an opening in the conical bottom of the receptacle and beengaged by the weight, a casing at the bottom of the lam p-bod y, intowhich one arm of said bracket projects, and a spring encircling saidlast-mentioned arm and adapted to force the bracket upwardly against theweight, substantially as set forth.

4. The combination, with a lamp and an extinguisher adapted to embracethe wick-tube, of rods adapted to engage said extinguisher, a bracketattached to said rods, a chamber having a conical bottom and adapted toreceive one arm of said bracket in the bottom thereof, a sphericalweight in said receptacle, a casing removably attached to the bottom ofthe lamp-body, and a spring in said casing adapted to force the bracketand attached rods upwardly, said spring being of a tension less than theforce exerted by the spherical weight, substantially as set forth.

5. The combination, with a lamp and an extinguisher adapted to embracethe wick-tube, of rods adapted to engage the extinguisher, a brackethaving arms provided with sockets for the reception of the lower ends ofsaid rods, a sphere for normally holding the bracket in its depressedposition, and ayielding device for elevating said rods when the sphereis moved from its normal position, substantially as set forth.

6. The combination, with an extinguisher, rods connected thereto, and aspring or springs for elevating said rods, of a chamber having a slopingbottom and a sphere fitting snugly between the top and bottom walls ofsaid chamber and adapted when in its lowest position to rest on aprojection from the rods and hold said rods depressed, substantially asset forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
